A R C H I V E S

Today's APOD is an Extra Detail Magnification (or "EDM", for short) of yesterday's beautiful Contextual Frame that was taken by the NASA - Mars Reconnaissance Orbiter during the late Martian Southern Spring (such as January, 24, 2015 on Earth), when the Red Planet is near its Perihelion (---> the closest distance to the Sun). For more information about this unusually-looking Martian Feature, please refer to the APOD of February, 14, 2015.

Mars Local Time: 15:32 (Middle Afternoon)
Coord. (centered): 67,861° South Lat. and 207,704° East Long.
Spacecraft altitude: 250,9 Km (such as about 155,808 miles)
Original image scale range: 25,1 cm/pixel (with 1 x 1 binning) so objects ~ 75 cm across are resolved
Map projected scale: 25 cm/pixel
Map projection: POLAR STEREOGRAPHIC
Emission Angle: 8,9°
Phase Angle: 46,3°
Solar Incidence Angle: 53° (meaning that the Sun was about 37° above the Local Horizon at the time the picture was taken)
Solar Longitude: 265,8° (Northern Fall - Southern Spring)

Additional process. and coloring: Lunar Explorer Italia

This picture (which is an Extra Detail Magnification of a NASA - Original Mars Reconnaissance Orbiter b/w and NON-Map-Projected CTX frame identified by the serial n. ESP_039568_1120-1) has been additionally processed, magnified - in order to make the details more visible -, contrast enhanced, Gamma corrected, and then colorized in Absolute Natural Colors (such as the colors that a human eye would actually perceive if someone were onboard the NASA - Mars Reconnaissance Orbiter and then looked down, towards the Surface of Mars), by using an original technique created - and, in time, dramatically improved - by the Lunar Explorer Italia Team.
